Hop-Up/Spring upgrades; specifically JG416

Newbie Tank

Okay, here we go again with another noob thread. Anyway. Searched the threads about looking at hop-up rubbers to little avail. (If someone finds a link, I humbly apologize)

My question here is that I've invested in a V2 JG 416, but having run through the massive thread that is the JG416 review, I know that the accuracy isn't good out of box, and the gun is too hot for field use; nearing 400fps.

Now I can't recall off the top of my head what Op-For rules are on upgraded FPS values are, but I'd say I'm looking in the area of 360-370, 380 MAX. So being the dumb person I am, what spring would I be looking for?

Okay, now the other question. I was on ehobbyasia looking for a new hop-up assembly to put into the gun, and I'm sort of puzzled. I know I should buy a hop-up unit, but what type of nub should I buy? It seems there's these numbers regarding the "hardness" of the rubber? Described as "45/55/65 Hard," and I am going to assume that it will affect the degree to which the BB "hops" up.
So what should I be getting? I'm mostly going to be doing plinking at the moment at home and down the road will game it outdoors in the summer.

Thanks a lot guys!

It is old and does not have all current day brands but its enough that you should be able to get an idea of how and springs are labeled what they are. Even though its not in the chart, a modify S100 would put you in the ballpark area of 360-370.

I am not extremely heavy on knowledge about hop up rubbers, so I will let someone with the appropriate knowledge handle that area. If I may make a suggestion though, the guarder clear hop up rubber set is an excellent choice for anything firing under 400FPS.

Thanks T7! Your review on the 416 was really helpful too, thanks for putting that together.

And for the hop-up, I'd need a hop up chamber obviously, but what is the part that I need that would actually invoke the backspin?

Thanks again.
